WebSep 30, 2024 · Frequencies requested for this station class must be coordinated with the Aerospace and Flight Test Radio Coordinating Council (AFTRCC). Please see … WebRadiofrequency interference (RFI) is a form of EMI when the electromagnetic waves involved are in the radio frequency band of the electromagnetic spectrum. The frequencies of radio waves widely range from 3 kilohertz to 300 gigahertz. The terms EMI and RFI are often used interchangeably, but the former is commonly used.
